the lower ends of thebrac- Securely bolted to the beams 7 and arranged inspaced relation with .the angular plate 18` is a guiding ing in which is mounted a screw2i, one end of whichfis provided with a head 25, form- -ing a reduced neck portion 26 which is vertical 'ada ted to be'arranged' within an openingv 1n tiie'platel 27, the head-ofthe bolt being disposed within an opening formed in the portion of the plate 18. v Secured to the-outer end of the vscrew 2li-is a removable head- 28 which may be either rectangular in form, or of any other suitable formgdesired so'that a wrench 'or other tool 4 may be quickly applied theretoand rotate.'

the screw, `and brace thelower end of 'the .bracing members 4.

lIt will be'readily apparent that when is desired to move the form, the beams 7 are released from the'stake 12 by withdrawing theftapering keys 29 whichare insertedl bev' 1 tween the ends 12. A cross pin 30 is arranged 1n the upperof-the beams and the stake end of the stake 121to prevent any upward movement of the buter ends of the beams 7.

In forming the inside pilasters, which'k carrythe beams, girders and the concrete' floor slabs or hollow tile, I provide a horizontal-member 31, the inner edge of which is supported by theV walls 1, while the body portion thereof may be supported tingany .suitablel manner.' Thus, as the walls'of the buildingy are formed, the inside pilasters may be also formed atthe same time.v `After the walls ofthe building Yhave been,

formed.v up tothe first iioor, the formsare then put in place upon the second floor and arranged in alinement vandy lined with the walls of the lower floor. When this is done .the stake 12- is eliminated as the fastening means for holding the beams 7 in place and' in place of the stake 12, the beams are seeurely heldby-means of a bolt 32 which is adaptedto passdown through a block-33 arranged between the beams 16 and which is provided 'with tapering vside walls.- The bolt 32 passesvthrough the beamsl 7v and through the member' .31 and inpassing through the 'concrete ooring of the' first story, a pipe 34 is mountedfupon the bolt 's0 that the'same may be readily withdrawn.'

The bolt also extends through the member 31 so as *to rigidly hold the beams 7 in position. Driven in between the spacing blocks 35 and the block 33 are the tapering keys 36 which are adapted-to securely hold the bolt 32 against 'movement and at the Same time rigidly secure the beams 7 to the member 31 and the floor slab 37. t

In Fig. 6 I have illustrated a slightly rmodified form of means for adjustably securv ing the lowerends of the brace members 4:.'

'65 this form substitute a wooden-bleek 38 member- 23 provided with a threaded open'y for the angular plate18. This 'block 38 is.` I I mounted upon the lower ends of the brace members 4 and securely heldy inpositionby means of the bolt 17. The lower end of the ars 13 and the elongated washer be the same as shown and described vpositions. 4The mounting of the Inusin my improvedconcrete form theAk same is aced in position ready for use as clearly wall u tothe first floor .haslbeenformed The 'side `walls of theform are then Aremoved and placed upon the floor slab 37, the

beams A7 being firsts released by removing lthe taperingv keys 29 and disenga ing the stirrup20 from theupper end of t e stake 12. After the forms have been raised to the second floor the beams 7 are secured-in place by insertin the bolts 32 through the beams and throug the floor slab 37 andthe :mem-y ber 31. Thekeys 36 are then arranged'in' ppsition lto securely'` hold. the beams 7 in It will be readily apparentfrom the foregoing description, taken inl connection with f ,100 provideda simp e and durable adjustable` the accompanyin drawings, .that I have supprtin Vdevicetfor concretemolds whereby the e walls-.of thel molds willbe selustrated in Fig. V1.

ing the pouring and hardening of the concrete. It will also be apparent thatthe device can be'quickly andreadily set up ready for use or easily taken down when 1t is desired to'tlransport-the device from place to place.

It vice is extremely sim le in construction and can be manufacture low cost. A

Whiley i, have shown and described the.

preferred form' of my invention, -it will be obvious that various changes-inthe details of construction and in the proportlons may be rescrted to for successfully carrying my inventlon into practice without sacrificing at a` comparatively any of the novel .features or departing. from. Y

the scope of the appended claims.

Havi thus fully described my invention what I c aim'and desire to secure by Letters Patentis: 1 v' y 1. A ydevice of the class described including a mold wall, an upri ht ost arranged upon the outer side of` sal wa l, supporting beams hingedlysecured to the l'ower end of' said post, means for rigidly* securing.. the

bers, a bolt removably connecting the plate and the lower ends of the brace members to the supporting beams, and an adjustin screw carried by the su porting beams an engaging the plate to a just the lower ends ofthe brace members with respect to the beams.

2. A device of the class described including a mold wall a post arranged upon the si e of said wall, supporting beams having the inner ends hingedly secured to said post, means for securing the' outer ends of said beams, brace members having 4their upper ends secured to said post, spacedl guides secured to the outer ends of said beams yanangular' plate secured to thel loweil end of said brace 'membersf a bolt extending through'the plate and the lower end of the brace members and belowthe guides, an'

elongated washer disposed between the head of the bolt and the guides, and an adjusting screw movably mounted upon the outer ends ofthe supporting beams and having its inner end engaging the angular plate whereby the adjustment of said screw will rigidly adjust the lower ends of the bracing members.
